Dichlorido[(S,RS)‐1‐diphenylphosphino‐2‐(ethylsulfanylmethyl)ferrocene]palladium(II)

The reaction of enantio­merically pure planar chiral ferrocene phosphine thio­ether with bis­(aceto­nitrile)­dichlorido­palla­dium yields the title square-planar mononuclear palladium complex as an enantio­merically pure single diastereoisomer, [PdFe(C5H5)(C20H20PS)Cl2]. The planar chirality of the ligand is retained in the complex and fully controls the central chirality on the S atom. The absolute configuration, viz. S for the planar chirality and R for the S atom, is unequivocally determined by refinement of the Flack parameter.
